A severed limb was spotted this week floating not far from the Olympics sailing venue in Rio de Janeiro's Guanabara Bay.
According to the Independent, residents of Governador Island, which sits in the bay just a few miles from the start of the sailing races, found the leg that had been severed at the hip on Sunday.
"It was probably someone murdered by the drugs gangs, who was dumped in one of the rivers that flow into the bay," a police source told the Daily Mail this week.
Police say they are doubtful they'll be able to identify the person the leg once belonged to, despite the appearance of a tattoo that read "Kauan" on the leg's calf.
"It is very common to find body parts in the Guanabara Bay," the police source told the Daily Mail.
